Type DMB (45°C)
i-BARATRON® DIGITAL CAPACITANCE MANOMETER
The MKS Type DMB i-Baratron® Capacitance Manometers are RoHS-compliant dualoutput products with both ODVATM-certified DeviceNetTM digital communications and legacy
0-10VDC analog output signals. Available in three different operating temperatures for
different applications, the DMB products use an efficient microprocessor-based digital
structure that provides exceptional stability and repeatability under demanding conditions
such as semiconductor manufacturing equipment. The DMB manometers use the patented
MKS all-welded Inconel® diaphragm sensor, which has exceptionally high resistance to
corrosion from common process chemicals and is able to tolerate bursts of pressure to as
much as 45 psia (310 kPa) without suffering physical damage or permanent calibration
shifts. Two different models of the product are available: DeviceNetTM digital communications
or legacy 0-10VDC analog output. On DeviceNet models, main power and communications
are fed through a bayonet-style 5-pin electrical connector on the top surface of the Baratron.
On analog versions, power input and output are available on either a 9-pin or 15-pin D-subminiature electrical connector also on the top surface of the product. The product’s sensor
is internally heated and regulated to 45°C, and offers full-scale pressure ranges from 1000
to 0.1 Torr (133 to 0.013 kPa). The product is CE marked and is compliant with current EU
RoHS (Restriction of Hazardous Substances) regulations.
Features & Benefits
• Excellent long-term stability
• Internal operating temperature of 45°C
improves stability and increases resistance to process contamination
• Full-scale pressure ranges from 1000 to
0.1 Torr (133 to 0.013 kPa) for precise
measurement of low pressures
• All-Inconel sensor offers extremely high
resistance to corrosion from common
process gases
• Fast warm-up time allows system to be
available for production sooner
• High overpressure specification of 45 psia (310 kPa) prevents shifting or permanent calibration changes
• Electronics are microprocessor-based for best accuracy and repeatability
• Choice of ODVA-approved DeviceNet
digital communications or 0-10VDC
analog output
• OneTouch zero pushbutton
• CE approved and RoHS-compliant
